3:1 Flame Retardant Heat Shrink Tubing

3:1 Heat Shrink Tubing Dual wall (adhesive lined) 3:1 heat shrink tubing is made from a specially formulated, cross-linked polyolefin that is co-extruded with a meltable adhesive sealant. It offers excellent electrical, chemical and physical properties. This tough, flexible, flame retardant tubing can be used for electrical insulation, wire bundling, lightweight harnessing, and wire strain relief in a variety of home, commercial, industrial and military applications.

3:1 heat shrink tubing will slide easily over inline splices and connectors, and shrink down to 33% of its original diameter to fit snugly over any wire, hose or cable management project.

When heated and the tubing begins to shrink, the inner adhesive layer begins to melt and flow (similar to hot melt glue). When the tubing has shrank and cooled, the inner layer forms an adhesion layer between the tubing and the wire or component, providing a protective water-tight seal.

It is an excellent way to terminate the ends of your Braided Sleeving, creating a tight, professional finish.

The flame retardant jacket of 3:1 heat shrink tubing is tested and approved for use under UL VW-1 and CSA OFT material standards. Additionally, it is in compliance with RoHS, the European directive on the Restriction of Hazardous Substances.

For other heat shrink options, please see our 2:1 Heat Shrink Tubing, our 2:1 Semi-rigid Kynar Heat Shrink, our 2:1 Neoprenen Heat Shrink Tubing, our 3:1 Single Wall Heat Shrink Tubing, our 3:1 Flexible Flame Retardant Heat Shrink Tubing and our 4:1 Single Wall Flame Retardant Polyolefin Tubing.
